The European-manufactured product is being used for the wall construction, covering a total 15,851ft2. Steel is used for the roof.
Playvalue Toys president Doug Jones said he opted to incorporate CLT after being introduced to the product at an Ontario Wood WORKS seminar in November 2011.
He said it offered many benefits, including thermal efficiency, aesthetic appeal and "very good" fire performance.
David Moses, principal in Moses Structural Engineers, said integrating CLT load-bearing walls with steel deck and open-web steel joists on the project was straightforward. "It did require us to develop a few new design details for connecting the two materials and also new guidelines for locating steel components relative to joints in the CLT wall panels," he said.
"We also had to keep the design simple for installing the steel, especially since the high parapets were part of the CLT wall panels and the steel joists were dropped into place after the load-bearing CLT walls were installed."
Professional engineer Michelle Maybee, a technical adviser to Ontario Wood WORKS/Canadian Wood Council, said she was aware of other design teams that were considering using cross-laminated timber.
"Projects that use CLT will increase our knowledge of the product, both the benefits and the challenges, and will demonstrate that wood products and systems can be cost-effective solutions for non-residential projects," she said.
